Harrison Ford - While presenting Favorite Voice from an Animated Movie with Shia LaBeouf, Ford replaced an orb containing the winner with a blimp, similar to the classic scene in Raiders of the Lost Ark. Also like that scene, a "booby-trap" bucket of slime was dumped onto his head. Ford joked about it and LaBeouf gave him his trademark fedora.

Brendan Fraser - While presenting Favorite TV Show with Rihanna, who was carrying an umbrella, Fraser asked why she had one. The singer slyly replied that "this is for you", and a stream of slime rose from the podium and hit Fraser's forehead.

Orlando Bloom - Bloom was the mystery celebrity at the end of the show who got slimed with 27 gallons of the green goo alongside Jack Black.

Jack Black - The host was slimed at the end of the show with the 27 gallons of slime collected from the slime stunts with Orlando Bloom.

The Rocktopus is an eight legged octopus of rock n' roll who haunts Jack Black in his dreams. Later during the awards show, they settle their differences in time for the Rocktopus to activate the slimer machine.

The iCarly cast was live outside the Pauley Pavilion in Hollywood, where the 2008 Kids' Choice Awards were held. The cast aired from 9/8c - 11/10c. Carly, Sam, Freddie, and Spencer were at the Kids' Choice Awards because Spencer was hired to make a Kids' Choice Awards Blimp out of Wieners. Although Spencer was working on his sculpture, he happened to peek around the show, like the Gift bags for the Celebrities, going into Jack Black's Dressing Room, and stealing some mini wienies from the Snack table. In the end, his sculpture was destroyed when the Snack lady attacked him. People actully believed that it was a fan who destroyed the sculpture as security tackled the Snack Lady.
